Abstract
This invention provides a plated steel wire with high corrosion resistance and excellent workability, wherein the average composition of the plating alloy in the plated steel wire comprises, in terms of weight percentage, Al: 4-20%, Mg: 0.8-5%, and if necessary one or more from among Si: ≦2%, Na: 0.001-0.1% and Ti: 0.01-0.1%, with the remainder Zn, and an Fe—Zn alloy layer of no greater than 20 &mgr;m thickness is present at the plating-base metal interface; it is produced by coating a steel wire with a molten zinc plating composed mainly of zinc as the first stage and then.coating it with a molten zinc alloy plating with the aforementioned average composition as the second stage. The maximum plating bath immersion time is 20 seconds, and the part of the plated steel wire drawn out from the plating bath is purged with nitrogen gas.
